|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility prints a sequence of numbers, one per line
|
|
.Pq default ,
|
|
from
|
|
.Ar first
|
|
.Pq default 1 ,
|
|
to near
|
|
.Ar last
|
|
as possible, in increments of
|
|
.Ar incr
|
|
.Pq default 1 .
|
|
When
|
|
.Ar first
|
|
is larger than
|
|
.Ar last
|
|
the default
|
|
.Ar incr
|
|
is -1.
|
|
.Pp
|
|
All numbers are interpreted as floating point.
|
|
.Pp
|
|
Normally integer values are printed as decimal integers.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility accepts the following options:
|
|
.Bl -tag -width Ar
|
|
.It Fl f Ar format
|
|
Use a
|
|
.Xr printf 3
|
|
style
|
|
.Ar format
|
|
to print each number.
|
|
Only the
|
|
.Cm E ,
|
|
.Cm e ,
|
|
.Cm f ,
|
|
.Cm G ,
|
|
.Cm g ,
|
|
and
|
|
.Cm %
|
|
conversion characters are valid, along with any optional
|
|
flags and an optional numeric minimum field width or precision.
|
|
The
|
|
.Ar format
|
|
can contain character escape sequences in backslash notation as
|
|
defined in
|
|
.St -ansiC .
|
|
The default is
|
|
.Cm %g .
|
|
.It Fl s Ar string
|
|
Use
|
|
.Ar string
|
|
to separate numbers.
|
|
The
|
|
.Ar string
|
|
can contain character escape sequences in backslash notation as
|
|
defined in
|
|
.St -ansiC .
|
|
The default is
|
|
.Cm \en .
|
|
.It Fl t Ar string
|
|
Use
|
|
.Ar string
|
|
to terminate sequence of numbers.
|
|
The
|
|
.Ar string
|
|
can contain character escape sequences in backslash notation as
|
|
defined in
|
|
.St -ansiC .
|
|
This option is useful when the default separator
|
|
does not contain a
|
|
.Cm \en .
|
|
.It Fl w
|
|
Equalize the widths of all numbers by padding with zeros as necessary.
|
|
This option has no effect with the
|
|
.Fl f
|
|
option.
|
|
If any sequence numbers will be printed in exponential notation,
|
|
the default conversion is changed to
|
|
.Cm %e .
|
|
.El
|

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
command first appeared in
|
|
.Tn "Plan 9 from Bell Labs" .
|
|
A
|
|
.Nm
|
|
command appeared in
|
|
.Nx 3.0 ,
|
|
and ported to
|
|
.Fx 9.0 .
|
|
This command was based on the command of the same name in
|
|
.Tn "Plan 9 from Bell Labs"
|
|
and the
|
|
.Tn GNU
|
|
core utilities.
|
|
The
|
|
.Tn GNU
|
|
.Nm
|
|
command first appeared in the 1.13 shell utilities release.
|
|
.Sh BUGS
|
|
The
|
|
.Fl w
|
|
option does not handle the transition from pure floating point
|
|
to exponent representation very well.
|
|
The
|
|
.Nm
|
|
command is not bug for bug compatible with the
|
|
.Tn "Plan 9 from Bell Labs"
|
|
or
|
|
.Tn GNU
|
|
versions of
|
|
.Nm .
